Nintendo Download: ZombiU demo, NBA 2K13 demo, more

Nintendo continues to play catchup to the PlayStation Network and Xbox Live Marketplace when it comes to offering downloadable demos. But today’s Wii U eShop update adds two new try-before-you-buy titles to the service: Ubisoft’s ZombiU and 2K’s NBA 2K13.

This is great for Wii U owners as you really have to try ZombiU’s unique mix of GamePad inventory management and first person shooting for yourself.

You can see what else is available as part of this week’s Nintendo Download (on the 3DS, DS, and Wii) after the break.
